ROBERT H. HOWARTH, OF ROTHSCHILD, WISCONSIN.

CORE FOR. PAPER-ROLLS.

Appncation filed February 21, 1914.

, Toul? 'whom 'it 'may concer/i Be .it known that I, ROBERT ISI. HowAn'rr-r, a citizen of the United States, residing at Rothschild, in the county1 of Marathon and State of Wisconsin, have invented certain .new and useful Improvements in Cores for Pa )er-Rolls; and I do hereby declare the foliowing tobe a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it ap pertains to make end use the same.

My invention relates to cores for use in paper rolls, especially in connection with those paper rolls which are used in the production of newspapers, or rolls of wrapping paper, o r the like, where it desired to posltively drive the core from any suitable Sourcecf power while the material is being wound thereon.

lt is my intention to provide a light, cheap and etlicient coremade of rolled paper, pasteboard, or the like, and which can be nianufactured in any convenient lengths, and then cut into shorter lengths and i'itted to suit the various axial lengths of the paper rolls for which such cores are intended; or a series of these cores may be used to form a composite core, all mounted on the saine spindle. l

My invention will be understood by reference to the accompanying drawings, in which the same parts are indicated by similar reference symbols throughout the several views.

Figure l is a side elevation showing several. ot' the cores assembled on a single shai't lior use in a paper mill, parts being broken away; Fig. 2 is a 'detaii showing one oit the cores removed from the spindle; Fig.v 3 is a side elevation showing the core mounted onthe spindle, the paper roll inclosing the core being omitted, and parts being .broken away; Fig. d shows a section through 'the core and the centering collars, the spindle being' shown in elevation, paris being broken away, and the section being along the line 4--11 of Fig. 3; Fi g. 5 shows a section through the corey'along the line w et Fig. i looking in the Vdirection of the arrows, the spindle and centering collar being omitted; and F ig. 6 is a detail View showing the metal reinforcing sleeve designed to be mounted in the end ol? the pasteboard roll.

A. represents the shell of the core which is made of pasteboard, or other similar ma terial, preferably spirally wound of six or Specification of Letters Patent.

eight thicknesses ol. heavy paper, wound in reverse direction to break joints and insure stillfness, and cut in the desired length. This shell is cut away at each end, as at a, to receive the lug il of the centering collar D, which is secured on the spindle (l in any convenient why, as by means of the set screw ll. In the ends of the shell A the metal sleeve B is mounted, which sleeve is cut away at one end, as at b, and part of the cut-away portion is upwardly bent, as at b', to form a metal wear surface for the sides 0, of the slot a, in the shell A. This sleeve slips over the reduced portion D of the centering collar l.) and the curved flanges b serve as wear plates to protect the edges a of the slot (t against wear `l'roln the lug d projecting axially .t'roin the shoulder d of the collarl), as shown most clearly in Fig. 3.

The spirally-wound pastehoard tube may be made as long as desired, and then may be cut up into the desiw'l lengths, and the ends ot' each section ma, oe then cut away, as at fr, and suitable sleeves l inserted; and these sections so constructed may be slid over the end olf the spindle C and secured and centered on same by means oi the collars D with the lugs (Z.

' It will bcobvious that various 1nodilications might be made in the herein described apparatus, and in the construction, combination and arrangement of parts which could be used without departing from the spirit ol? my invention.

Having thus described my invention what l claim and desire to secure by Letters Patent ol" the United States is l. The combination with a core compris ing a. hollow shell composed of a series ot strips ot' heavy paper spirally wound in, reverse itlireetion and axially indented at each end. with a rein forcing metal sleeve snugly fitting in the end olE said core and axially indented to register with the indentations in said paper core, and having curved Hanges engaging the sides ol said axial indentations in said core and holding said sleeve in place, and protecting said core from wear, of a spindle passing through said hollow shell, and collars secured on said spindle, and having lugs projecting into said indentations in said core, and said sleeve, sub stantially as described.
